Prospective interview and follow up by postal questionnaireĮpidural analgesia for labour and delivery did not seem to be associated with back pain 1-2 months postpartumġ4% v 7% at 6 weeks (relative risk 2.22, 95% CI 0.89 to 5.53) Though new long term backache is reported more commonly after epidural analgesia in labour it tends to be postural and not severeĭata extraction from 1990 survey paper and re-examination

Retrospective questionnaire plus outpatient consultation Relation between backache and epidural analgesia is probably causal Result for backache (epidural v no epidural) Despite these adjustments, the association between epidural pain relief for labour and the reporting of long term low back pain remained.
The authors were aware that this association might not be causal, and they attempted to control for possible confounding factors by statistical adjustment. They were unable to make any assessment of the severity or aetiology of the low back pain. They found an unexpected association between the use of epidural pain relief for labour and long term low back pain (lasting more than three months). 3 They carried out a postal questionnaire survey of 12 000 women who had delivered in Birmingham between 12 months and 9 years earlier.
MacArthur et al first suggested that epidural analgesia might be associated with low back in 1990. There have been several studies into back pain and epidural analgesia (table (table1). 1 However, not much is known on long term effects of this form of pain relief, and before this study anecdotal or case series had concentrated on more severe side effects, such as extremely rare neurological complications. Epidural analgesia in labour is used by about 100 000 women in Britain each year.
